(Palm mute)

C                  Gm

C                    Gm
From small shocks to surgin' bolts
Fm                            Gm
These are the signals from my spinal post
C                                 Gm
Sent down the wires through their lines and folds
Fm                Gm
Into a riot on my frontal lobe

I'm going through the motions
